The Sept. 1 event will feature more than a dozen performers over two stages at Philly's Hersheypark Stadium, including Buckcherry, Daughtry, Fuel, Puddle of Mudd, Black Stone Cherry, Foxy Shazam, Redlight King and Otherwise. More artists will be announced, according to the event's website.

General admission tickets and VIP packages are available now via Ticketmaster.

"Hershey and its surrounding markets love rock 'n' roll, and we wanted to give them a festival that will feature the best live rock around," Gary Spivack, Co-President of Right Arm Entertainment, said in a press release. "From bottom to top, Rock Allegiance is stacked. We want everyone to come spend part of their Labor Day weekend with us in what will be the biggest rock festival the area has ever witnessed."

The headlining gig will be among the first few shows of Stone Temple Pilots' summer outing in celebration of the 20th anniversary of their multi-platinum debut, "Core."
